Hi BH,
This is an integer frequency, 2.08MHz is not a fractional spurs.
You can try the following, if they don't help, likely the spurs is coming from somewhere else on your board.
- Set PFD_DLY_SEL = 1
- Set MASH_ORDER = 0 (integer mode)
- Set R58…
Part Number: DAC39RF10 Tool/software: Hi team,
1. In Phase-continuous NCO Update Mode, is it possible to change NCO while having RF output? Or should it better to stop the RF power and then change (hop) the NCO? 2. How much interval should the device…
Part Number: DAC39RF10 Tool/software: There is a whole section in the datasheet for how to perform an eye scan. Is there a tool that TI has available that can create the resulting eye diagram for the DAC39RF10 after the eye scan?

Dear Matthew,
Sorry for my late reply ,but I have been unable to continue with tests until today. I will try to describe our setup, and configuration used.
- Serdes rate : 10.65Gbps
- Data rate : 8.52Gbps
- FPGA clock : 133.125 MHz (the GUI give us a wrong…
Part Number: DAC39RF10-SP Tool/software: Hi,
Could you check register map for spur issue at 2MHz from center.
input clock is 8388.608MHz from LMX2615.
it's occurred under only low temperature.

Tool/software:
Hello,
My customer is testing the signal output of the DAC39RF10 device alone on a board they designed.
They used the settings below, which were confirmed to be output normally in standalone mode on DAC39RF10EVM…
Part Number: DAC39RF10 Tool/software: Part required is DAC39RF10ACLEP however we were suggested DAC39RF10-SP as the part is required for space program. Qty required is 10 Nos. The part you suggested is DAC39RF10ACLNEP . What is full form of NEP? Is part…
Hello Ak,
DAC39RF10-EP is the generic part number for the Enhanced Product or "EP" version of our DAC39RF10. The orderable part number for DAC39RF10-EP will be DAC39RF10ACLNEP. This product is not orderable yet, it will be orderable upon release…
